"That Year, the Twilight Was Dark" tells the story of Lin Mu-sheng and Ye Wan-xing's youthful past, which they met during summer volunteer teaching training, became connected through poetry, and regretfully missed in reality and misunderstanding. Lin Mu-sheng is rational and calm, while Ye Wan-xing is sensitive and has low self-esteem. The two gradually develop feelings for each other through correspondence. However, the disparity in family background, the opposition of his parents, and Ye Wanxing's deep self-denial due to a childhood misunderstanding eventually led to a break in front of the barrier of reality. In the past ten years, the two have started their own families and taken different life trajectories. It wasn't until an email that she didn't expect a reply that the truth of the tragedy was revealed - a cruel misunderstanding about "purity". The story depicts the purity and fragility of youthful love in a delicate way, and explores the themes of growth, class, family and self-reconciliation. Twilight is like poetry, but also like fate. They finally learned to coexist with regrets in time.
Concept: Class differences and misunderstandings of destiny are intertwined, and youthful love eventually turns into regret. They met in the twilight and separated in the twilight. They could only learn to reconcile with the past in their respective lives.
